Description

FIELD

The subject matter relates to wireless communications, and particularly relates to a wireless network device.

BACKGROUND

Wireless communication is widespread. An LTE (Long Term Evolution) module for receiving and/or transmitting wireless signals needs to be connected to a power module to obtain a power supply. The LTE module and the power module are generally connected through engagements of bumps and slots. However, the LTE module cannot rotate relative to the power module in this engagement mode. In other words, an angle and direction of the LTE module relative to the power module cannot be adjusted. So the signal strength cannot be improved by adjusting the angle of the LTE module when the signal is not good.

Referring to FIG. 2 and FIG. 3, the exemplary power supply module 200 further includes a main body 1. The base 2 is positioned on the main body 1. The base 2 includes a fixed seat 21 and a rotating seat 22. The fixed seat 21 is positioned on the main body 1. The rotating seat 22 covers on the fixed seat 21. The rotating seat 22 can be rotated relative to the fixed seat 21. The rotating seat 22 and the fixed seat 21 are connected by snap structures.

The fixed seat 21 is substantially concave and in the shape of an upside-down bowl. A bottom of the bowl faces the rotating seat 22. A portion of the fixed seat 21 is received in the rotating seat 22. In the exemplary embodiment, the fixed seat 21 is integrated with the main body 1. In other exemplary embodiments, the fixed seat 21 may be detachably installed on the main body 1.

A slot 211 is defined on an end of the fixed seat 21. The slot 211 is adjacent to the main body 1. The slot 211 is recessed inwards from a periphery of the fixed seat 21. The slot 211 is substantially necking.

The rotating seat 22 includes a bottom board 221 and a sidewall 222. The sidewall 222 extends from a peripheral edge of the bottom board 221. The sidewall 222 is substantially a circular ring. The bottom board 221 and the sidewall 222 together substantially form an upside-down bowl. A bottom of the bowl faces the LTE module 300. The case 5 is installed on the rotating seat 22. The case 5 can be rotated relative to the rotating seat 22. A free end of the sidewall 222 is substantially necking to fit with the slot 211. The free end of the sidewall 222 is engaged and latched in the slot 211.

In this exemplary embodiment, the sidewall 222 is evenly divided into a plurality of buckles 223 by a plurality of gaps 2221. Free ends of the buckles 223 together fit with the slot 211. Free ends of the buckles 223 are engaged and latched in the slot 211.

The locked part 2231 facing the latch 213 can be elastically deformed. When the rotating seat 22 is rotated relative to the fixed seat 21 under an external force, the latch 213 serves to limit a rotation angle of the rotating seat 22. Thus, internal wirings (not shown) are not strained due to excessive rotation angle.

When the LTE module 300 is installed on the power supply module 200, the two second electrodes 72 are partly received in the two shaft holes 226. The two second electrodes 72 are electronically engaged with the two second conductive parts 342. The LTE module 300 can be freely rotated relative to the power supply module 200, with the two second electrodes 72 acting as an axis.

The LTE module 300 further includes a network interface 8. The network interface 8 is fixed on the circuit board 6. The network interface 8 is received in the case 5. An opening 54 is defined on the case 5 to expose the network interface 8. The network interface 8 serves to connect with a wired network.

FIG. 5 shows details of the first electrode unit 3, the second electrode unit 7, and the connection between the first electrode unit 3 and the second electrode unit 7.

Referring to FIG. 5, the positive pole 32 is positioned on a center of the supporting plate 31. The positive pole 32 includes an elastic portion 321 and a contact point 322. The contact point 322 is positioned on the elastic portion 321. The elastic portion 321 includes a combination of two side springs. One of the two side springs is straight, and the other one of the two side springs has a wave-like shape. When the first electrode 71 is rotated along with the LTE module 300 relative to the power supply module 200, the elastic portion 321 will be returned to its original position under an elastic force of the contact point 322, thereby avoiding poor contact between the elastic portion 321 and the first electrode 71.

The negative pole 33 is positioned on a peripheral edge of the supporting plate 31. The negative pole 33 further includes a connecting portion 332. The connecting portion 332 connects the two contact pins 331. The connecting portion 332 is substantially semicircular. The connecting portion 332 is attached on a side of the supporting plate 31. The two contact pins 331 are perpendicular to the connecting portion 332. The two contact pins 331 are fixed on the supporting plate 31. Each contact pin 331 is a combination of two side springs. One of the two side springs is straight, and the other one of the two side springs has a wave-like shape. When the conductive member 34 is rotated along with the rotating seat 22 relative to the fixed seat 21, the contact pin 331 will be returned to its original position under an elastic force, therefore avoiding poor contact of the contact pin 331 and the second conductive part 342.

A plurality of grooves 343 is defined on the first conductive part 341. Each groove 343 extends in a radial direction. The grooves 343 are arranged in a ring on the first conductive part 341. Each contact pin 331 of the negative pole 33 is partly embedded into one of the grooves 343. When the rotating seat 22 is rotated, the first conductive part 341 is accordingly rotated, and the contact pins 331 slide on the first conductive part 341 until entering into the grooves 343. In this exemplary embodiment, an annular portion of the first conductive part 341 which the grooves 343 define is convex towards the negative pole 33, thereby increasing contact area and contact stability of the contact pin 331 and the groove 343.

The first electrode 71 is a metallic plate. The first electrode 71 includes a fixing end portion 711 and a contact end portion 712. The fixing end portion 711 and the contact end portion 712 are opposite and away from each other. The fixing end portion 711 is fixed on the circuit board 6. The contact end portion 712 faces the positive pole 32, and the contact end portion 712 is electronically connected to the positive pole 32. In this exemplary embodiment, an end surface of the contact end portion 712 is arced. In this exemplary embodiment, microstructures are formed on the end surface of the contact end portion 712. The microstructures serve to promote and increase contact with the positive pole 32.

Each second electrode 72 includes a fixing part 721 and a contact part 722. The fixing part 721 is fixed on the circuit board 6. The contact part 722 is positioned on a side of the fixing part 721. The two contact parts 722 are located at the two sides of the first electrode 71. The two contact parts 722 are opposite and away from each other. The two contact parts 722 are electronically connected to the two second conductive parts 342.

Referring to FIG. 2 and FIG. 4, the exemplary wireless network device 100 of the present disclosure is assembled as follows:

The button 53 is pressed and the docking part 52 of the case 5 is inserted into the convex portion 224 of the rotating seat 22.

The button 53 is released to let the contact parts 722 of the two second electrodes 72 sink into the two shaft holes 226 and connect to the two second conductive parts 342.

When the signal is poor, an angle of the LTE module 300 relative to the power supply module 200 can be adjusted by swinging the case 5 and/or rotating the rotating seat 22.
